Drone & Industrial DC/DC Power Supplies – Levane Power

More Than Just Power: 20 Years of DC/DC Expertise – Building the “Power Heart” for Drones and New Energy Equipment

At the 2026 World Drone Congress, the booth of Shenzhen Levane Power Technology Co., Ltd. (Levane Power) was surrounded by visitors. They stared at the onboard power supply on display – a unit no larger than a few lunchboxes side by side, yet marked with an output power of 24kW.

A professional visitor stopped to look for a long time and asked the on‑site engineer: “How do you pack so much power into such a small volume?” The engineer turned the module over, pointed to the internal components and said: “All components are AEC‑Q automotive‑grade. The packaging and thermal structure went through over a dozen iterations – all to solve the power density problem.”

The visitor was impressed and immediately said he wanted to take a unit back for system integration testing.

Such conversations happen almost every day at Levane Power’s projects and exhibitions.

One thing, done for 20 years

In the early 2000s, the domestic DC/DC power market was dominated by imported brands. At that time, most power electronics talent flowed into consumer electronics, and very few companies were willing to focus on industrial‑grade high‑power power supplies. New energy was not yet a hot topic, and the shift to electric power had only just begun in a handful of pioneering companies.

But a small group of engineers started early, dedicating themselves to high‑efficiency, high‑power‑density, high‑reliability power conversion technology.

From 1kW to dozens of kW, from 12V to thousand‑volt high‑voltage platforms, countless technical iterations followed. Levane Power’s R&D team, through years of practice and iteration, has built a complete closed‑loop capability from high‑voltage input to low‑voltage output – covering topology, thermal management, EMI suppression, reliability validation, and more.

Two decades of technical accumulation have finally crystallised into a scalable product portfolio.

One product family: 3kW to 120kW full coverage

Many power supply vendors only offer mature products in a single power range. Customers often have to deal with multiple suppliers for different needs, significantly increasing system integration complexity. Levane Power has built one of the industry’s few full‑range onboard DC/DC product lines from 3kW to 120kW, supporting multiple output voltage platforms such as 24V, 48V, 58V and 400V.

At the 2026 World Drone Congress, the heavy‑load tethered drone solution featuring the 24kW onboard DC/DC power supply (HLF24K‑D50‑1000) drew particular attention. Under demanding high‑power conditions, it achieves around 97% conversion efficiency, keeping heat generation to a minimum.

Multi‑phase interleaved topology combined with precision control algorithms ensures output voltage accuracy within ±1%. Even when input voltage fluctuates sharply or loads change suddenly, the output voltage remains rock‑solid, providing stable power to mission payloads.

In the vehicle‑mounted power sector, Levane Power has also deep roots. Its 1kW‑15kW series products are widely used in refrigerated truck air conditioners, heavy‑truck auxiliary power supplies, and a large number of custom development projects for excavators, road breakers, and the conversion of construction machinery from fuel to electric.

Complete power range coverage means customers can get everything from small drones to large industrial equipment from a single source – significantly reducing the complexity of managing multiple vendors.

Reliability comes from systems and standards, not just “over‑specifying”

Simply over‑specifying components does not guarantee stable operation under harsh conditions. The key to reliability lies in engineering‑driven system design methods and a rigorous quality control system.

Levane Power adopts automotive‑grade development standards, and all key components are AEC‑Q automotive‑grade or industrial‑grade. Every power supply must pass a series of type tests before leaving the factory, including component stress analysis, thermal cycling, vibration and shock, damp heat, safety and EMC testing. In addition, in‑depth reliability validation methods such as MTBF analysis, FMEA, and HALT (Highly Accelerated Life Test) are integrated.

Many other power supply vendors follow commercial‑grade test standards – they perform well in the lab, but once deployed on real industrial or aviation platforms, they fail under high‑frequency vibration and extreme temperature swings. Levane Power’s products have been professionally validated for stability and reliability under varying temperatures and complex vibration conditions.

At the Shenzhen Drone Exhibition in May 2026, a customer asked: “How long can a power supply last?” Levane’s reply was straightforward: “The key components are designed for a life of more than 100,000 hours, but the power supply will age together with the whole system. The actual service life depends on the design life of the whole system.”

In the fiercely competitive low‑altitude economy market, “never letting you down” wins customer trust more than impressive datasheet numbers.

From ground to sky: full‑link power supply solutions

The bottleneck for long‑endurance tethered drones is often not the drone itself, but the stability of the entire power transmission chain: ground station – tether cable – onboard unit. If any link fails, the flight stops.

Levane Power provides not just power modules, but end‑to‑end system solutions. The ground station offers standardised power equipment from 5kW, 8kW up to 150kW; the onboard side is equipped with 3kW to 120kW power modules; the tether cable embeds composite fibre for simultaneous power and data transmission; and an intelligent monitoring system provides real‑time feedback on voltage, current, temperature and insulation status.

A provincial fire rescue team in China adopted a 3kW tethered drone platform primarily for night‑time fire‑scene lighting and emergency communications. Previously, battery‑powered drones could stay aloft for less than 30 minutes, wasting precious rescue time on battery swaps. After switching to Levane Power’s tethered supply solution, the drone achieved continuous hover operation for more than 8 hours, providing the frontline command with a persistent overhead view and real‑time fire data. The team reported that system stability and controllability exceeded expectations, and deployment time was reduced from the original 30 minutes to 15 minutes.

For industrial scenarios requiring even higher power, heavy‑load tethered drones with high‑power ground stations can perform complex missions continuously for several hours – no longer limited by battery life.

Custom and standard – two capabilities in one

While offering a full range of standardised products, Levane Power also has deep customisation capabilities.

Different drone platforms have vastly different flight control logic, voltage requirements and communication protocols. Levane’s R&D team can customise communication protocols and mechanical interfaces for major customers. The company has extensive customisation experience in agricultural machinery, construction machinery fuel‑to‑electric conversion projects, and range‑extender DC/DC systems.

This means that for major customers, Levane is not just a supplier, but a technical partner with strong R&D capabilities.

Final words

The low‑altitude economy is on the verge of take‑off. With thousands of drones taking to the sky, the demand for long‑endurance, high‑power, high‑reliability power supply systems will only become more urgent. In this race from “minutes of flight time” to “hours or even all‑day flight”, whoever provides the most stable and efficient “power heart” will have the chance to define the standard.

Levane Power has been dedicated to the DC/DC field for more than 20 years. Its product line covers all scenarios, from small tethered drones to heavy‑lift unmanned platforms, and has accumulated extensive deployment experience in domestic firefighting, grid inspection, emergency communications and other fields. From technical discussions at exhibitions to real‑world fire‑scene operations, from standard onboard modules to heavy‑lift custom solutions, Levane Power’s power systems are becoming a reliable power backbone trusted by countless users in aerial missions.

Whether hovering at high altitude or silently powering emergency rescue and industrial equipment electrification, Levane Power’s products always do the same thing: make complex, demanding power needs simple, reliable and sustainable.
